New to XML in Flash

Okay I need someone with some serious XML know how to help me with this one. I am creating a portfolio for my website and I want to have the portfolio in XML so you can either view it as thumb nails or a list. But I want the thumb nails to be Movie Clips that have roll over actions and so they need to be activated in flash. Also when you click on the thumbnail I would like it to preload the image inside the thumbnail box.

I have a test version at you can look at and let me know if it’s even possible. But I would really like to have it work so if someone can help me I would really appreciate it.

  []( - they have what I'm looking for in their portfolio page and I'm assuming it’s XML based.

  Thank you in advance
